Cessna 152 pilot reported a conflict with a King Air aircraft under tow while taxiing into the ramp area requiring evasive action to avoid a possible collision.

Narrative

We landed at ZZZ after a Part 91 flight in a Cessna 152. We were cleared by Ground Control to taxi to the Company X Ramp; which is accessible by Taxilane 1. Both the ramp and the taxilane are non-movement areas.The taxilane connects to the ramp facing the end of a double row of parking spaces; where the taxilane splits left and right to continue down either side of the parking rows. The left path has parking spaces on either side of the taxilane; while the right path has parking spaces on the left and a larger ramp with some maintenance hangars on the right. Our parking space is on the right side.Before turning off Taxilane 1; we could see the tail and upper portion of a King Air at the far end of our parking row. Concerned that it might be running and heading our way (pilots don't always call for clearance before moving in the non-movement area); we proceeded cautiously; and determined that the King Air was not moving. As we came around the corner; we confirmed that the King Air was not running; and was attached to a tug; past the far end of the parking row where there is additional ramp space. The King Air and tug were stationary; so we proceeded at a normal taxi speed towards our parking space; which is about halfway down the row.Just before reaching our parking space; the tug began pulling the King Air down the taxilane; directly towards us. The tug driver; who was seated with his back towards us; was not looking where he was going; and apparently did not see us.Our only option was to take evasive action and move as quickly as possible into our parking space to the left. Stopping or turning right would have kept us in the tug's path. Fortunately; the parking spaces on either side of mine were empty; giving us some room to maneuver. I kept a close watch on the King Air's wing as we turned into the parking spaces; and was relieved to see that the tug was turning in the opposite direction; towards the maintenance hangars. By my estimate; we were never closer than about 20 feet; and were that close only for a moment.After we shut down; we saw a man standing in front of the airplane. As we got out; he approached me:Man: Are you the pilot?Me: Yes.Man: You need to show me your pilot's license!Me: (Wondering if he is FAA or some other official) Who are you?Man: I am an employee of Company Y. That was an illegal and dangerous maneuver!Me: (Understanding he has no authority) I'm sorry; but I'm not required to show you anything.Man: Fine; I'll just look up your tail number!Me: Ok; go right ahead.The man walked away. As we finished securing the airplane; the tug driver drove over on his tug. After exchanging pleasant greetings:Tug: I am the night shift manager; and if I ever catch you doing something like that again; I will call the FAA and have them ground you!Me: Ok; you're welcome to do whatever you like.Tug: This is a non-movement area. We don't call for clearance; and I couldn't see you!Me: You didn't have any wing-walkers?Tug: We don't do that until we get to the hangar. If you want to make this a contest; we're bigger than you! Who do you think will win? We have security cameras!Me: As I said; you're welcome to do whatever you like.The tug driver then drove away so abruptly that a pair of large chocks was thrown sideways off the back of the tug.As I review this incident; I cannot think of anything I could have done better. I saw the King Air before coming around the corner; proceeded cautiously; and was prepared to turn around and move out of the way if necessary. After finding that the King Air was attached to a tug and not moving; I proceeded towards my parking space at the standard 'brisk walk' taxi pace. By the time the tug started moving; there was no choice but to move quickly into the parking spaces. Stopping or turning around would have left us in his path and could have resulted in a collision.I have also reviewed the incident with my passenger; who is also a licensed pilot; and he hascome to the same conclusions.I am very concerned about the unsafe behavior of the tug driver. He did not clear the area before starting to move; and did not use wing-walkers or safety spotters. The Company X ramp is very busy; and is home to several flight schools and private operators; with light aircraft coming and going almost continuously during daylight hours. Vigilant caution and good situational awareness are essential for safety on this ramp.I am also concerned that the tug driver disregarded; or was perhaps unaware of; the FAA's ground movement right-of-way rules described in AC 150-5210-20A 'Ground Vehicle Operations to include Taxiing or Towing an Aircraft on Airports' and the 'FAA Guide to Ground Vehicle Operations;' both of which clearly state that aircraft have the right-of-way and ground vehicles must always yield to aircraft (unless directed otherwise by ATC; but this incident took place in a non-movement area). These rules require the tug driver to ensure that his operation will not interfere with aircraft movement; and require him to stop and yield to an aircraft if there is a potential conflict.This unsafe behavior is even more concerning in light of the hostile and threatening actions of both the tug driver and the other employee of Company Y; both of whom clearly demonstrated several of the FAA's 'hazardous attitudes.'Suggestions for improvement: Better education of mechanics and tug drivers on the ground handling right-of-way rules; emphasizing the importance of establishing and maintaining situational awareness (including using wing-walkers or safety spotters); and the requirement to yield to operating aircraft.
